Abstract

L'invention concerne un dispositif (10) destiné à des examens électrophysiologiques sur des éléments biologiques (11), composé d'un support (12) sur lequel est disposé un réseau d'électrodes de mesure (14, 15), et d'un récipient (21) comportant une chambre de réception (24) pour la matière biologique (21) et le milieu de culture correspondant (25). Le récipient (21) est disposé autour des électrodes de mesure (14, 15) sur le support (12) de manière que ces électrodes soient en liaison électrique avec la chambre de réception (24). Une contre-électrode (38) disposée de manière permanente dans la chambre de réception (24) permet de mesurer des signaux électriques (S) entre les électrodes de mesure (14, 15) et la contre-électrode (38).
